Und3ertak3r,
I attempted a search for your problem also, but had less luck in finding anything than even you did.

I do have one possible solution, that may help though. I have attached a small program that is a registry cleaner (zipped). It is less than 700kbits but is very good. It will show you every piece of software registered and clean up all orphaned files and registry items. It has several other useful aspects also, that you might find useful. Its a little short on documentation, but I have been using it regularely for over a year with no problems. Have a look at it, and see if it might not help.

The only thing I found in my searching was some guy who couldn't update his AdAware, and it was suggested his host file was the culprit, which wouldn't be in your case as you are loading it from disk.
